I Am Number Four (Touchstone, Blu-ray or standard DVD, PG-13, 109 min.). This film is sort of The CW meets Michael Bay. Premise is a very hot looking teen alien (Alex Pettyfer as John Smith) is being hunted by deadly beings from his home planet of Lorien. While deadly, these Mogadorians unfortunately are rather silly looking, like skinheads with tattoos and gills next to their noses. There were nine alien children in all who fled their home world, but the first three have been killed and John is number four.

John and his guardian Henri (Timothy Olyphant of the excellent TV series “Justified”) pull up stakes from the coast and head for Paradise, Ohio, where John enrolls in high school and meets photography-obsessed Sarah (Dianna Agron of TV’s “Glee”); picked-on Sam (Callan McAuliffe), whose missing father had been helping Henri located the other refugees; and bully Mark James (Jake Abel), the school’s quarterback and Sarah’s former boyfriend. I like the relationships in the story, and the haunted hayride is fun, but director D.J. Caruso mishandles the beginning and the ending. The beginning is simply too dark, and the point of view is misleading, making you think something is going to crash on Earth. The ending is too much Michael Bay, with a battle worthy of a “Transformers” film that demolishes the school and goes for bang over coherence. There are some nice middle touches when John receives his legacies, special powers, such as the blue light and force that emanates from his hands, that make him super-human.

The Blu-ray version has six exclusive deleted scenes (18:58) with director introduction. Most noteworthy is one with Karen Allen (“Starman”) as Sam’s mother. There also is an 11:44 look behind the scenes of Tresa Palmer preparing to play Number 6 (she is the deus ex machina of the plot). Finally, there are 3:15 of bloopers, a standard DVD and a digital copy. Grade: film 2.75 stars; extras 2.25 stars

Gnomeo & Juliet (Touchstone, Blu-ray or standard DVD, G, 84 min.). Building on William Shakespeare’s “Romeo & Juliet,” the film has Ms. Montague and Mr. Capulet as not-on-good-terms neighbors on Verona Drive in Stratford on Avon. Both take terrific pride in their backyard gardens. Unbeknownst to the two, when they are away or asleep, their garden ornaments come to life, and Montague’s Blue gnomes have been battling Capulet’s Reds. However, one day Blue gnome Gnomeo (voice of James McAvoy) meets Red gnome Juliet (Emily Blunt) as she is trying to capture a wild orchard in an abandoned garden nearby. She goes into action ninja style, and he has just pulled off a commando raid against bully Red gnome Tybolt (Jason Statham).

There is a lot of fun here, including lawnmower races, and the movie features songs by Elton John, who served as executive producer and whose Rocket Pictures produced the film. Elton and Bernie Taupin wrote three new songs, including the fine “Hello Hello” and “Love Builds a Garden.” Also among the vocal talent are Michael Caine as Lord Redbrick, Juliet’s father; Jim Cummings as the flamingo the title characters rescue and befriend; and Ozzy Osbourne, Julie Walters, Hulk Hogan, Maggie Smith, Patrick Stewart and Stephen Merchant.

Blu-ray extras include two alternate endings; 42:26 of deleted scenes via story reels, with director Kelly Asbury (“Shrek 2”) introducing each; and outtakes and Osbourne discussing playing a lawn deer. Each version has looks at John’s participation (5:47) and Ashley Jensen giving voice to frog Nanette, plus a “Crocodile Rock” music video with John and Nelly Furtado. The Blu-ray set includes a standard DVD as well. Grade: film and extras 3 stars

Lemonade Mouth (Disney DVD, TV G, 107 min.). This made-for-Disney Channel movie follows in the “High School Musical” mode. It is about five high school students who meet in detention in the music room and decide to form a band. As always, one has to suspend belief because right from the very first song, without a rehearsal, they sound great. The band, which picks the name Lemonade Mouth, has to battle with an already established band, Mudslide Crush, at the school and with Principal Brenigan (Christopher McDonald). The band members are played by Bridgit Mendler (vocalist Olivia), Adam Hicks (keyboardist Wen), Hayley Kiyoko (bassist Stella), Naomi Scott (guitarist Mo) and Blake Mitchell (drummer Charlie). In the rival band, and sort of Mo’s boyfriend, is Scott, played by Nick Roux. All are appealing and the songs are above average, particularly Lemonade Mouth’s Halloween Bash performance. This is an extended version of the film, so after the credits there is an interview and song on “Music Scene.” One can also view the film with the lyrics displayed, and there is a digital copy of the film. Grade: film 3 stars; extras 2 stars

Rating guide: 5 stars = classic; 4 stars = excellent; 3 stars = good; 2 stars = fair; dog = skip it
